Hi,
Likely the easiest method of producing a trajectory file that you
can load into VMD is to generate an XYZ file, a very simple text
file format that is easy to write and to read:
http://www.ks.uiuc.edu/Research/vmd/plugins/molfile/xyzplugin.html
I have attached examples for you, to make a trajectory, you merely
need to repeat the structure of the file multiple times as I've done
for the trivial trajectory example (I just concatanated the original
structure multiple times).
Cheers,
John Stone
